Origin & Breeding History: 'Sunviobuho' originated from a cross between two proprietary breeding lines, made at Higashiomi-shi, Japan in May 2000. Seeds obtained from the cross were sown in August 2000 and 3 seedlings were selected based on their spreading growth habit, small flower size and blue and white petal colour. The seedlings were propagated by cuttings and grown in pots in a trial at Higashiomi-shi, Japan from October 2001. 'Sunviobuho' was selected from this group.
Tests & Trials: 'Sunviobuho' was tested during the spring of 2006 in St. Thomas, Ontario. The trial included 15 plants of each variety. All plants were grown from rooted cuttings transplanted into 11 cm pots on April 26, 2006. Observations and measurements were taken from 10 plants of each variety on May 30, 2006. All colour measurements were made using the 2001 RHS colour chart.
